Job Description

A well-established precision engineering subcontractor in Birmingham is seeking an experienced CNC Programmer / Setter to join a busy machine shop. You will work across a range of multi-axis milling and turning platforms, taking components from raw material through to finished part — programming offline, proving on the floor, and optimising cycle times to meet tight delivery schedules.

The business supplies customers across automotive, aerospace, and defence sectors, producing complex, low-volume and medium-batch components in steel, aluminium, titanium, and nickel alloys. This is a hands-on role with genuine scope to influence process and tooling decisions.


Machinery you will work on

Mazak Integrex i-400

Multi-tasking mill-turn, Mazatrol SmoothX control

DMG Mori NLX 2500

CNC turning centre, MAPPS V / Fanuc 31i control

Mazak Variaxis i-600

5-axis VMC, Mazatrol SmoothX, full simultaneous

Doosan DNM 6700

3-axis vertical machining centre, Fanuc 0i-MF

Citizen Cincom L20

Swiss-type sliding head lathe, Fanuc 32i control

XYZ 2-OP / ProTURN

Portable VMC and manual-assist turning, ProtoTRAK

CAM & software

Offline programming using Mastercam 2024 (milling and turning) — experience with multi-axis toolpaths (simultaneous 5-axis, swarf, steep & shallow) essential

On-machine programming in Mazatrol SmoothX and Fanuc conversational; ability to hand-edit G-code and M-code directly at the control

Renishaw on-machine probing and tool-setting cycles (RMP60 / OLP40)

Solid modelling in SolidWorks or similar for DFM feedback and fixture design

Tooling management via Zoller presetter data integration

Key responsibilities

Write, prove, and optimise CNC programs for milling, turning, and mill-turn operations from customer CAD models and 2D drawings

Set and change-over machines including tool assembly, offsets, work coordinates, and probing routines

Select cutting tools, inserts, and parameters — working closely with Sandvik and Kennametal technical reps

Carry out first-off inspection using Mitutoyo CMM and hand gauging; complete route cards and inspection records to AS9100 / IATF 16949 requirements

Reduce cycle times through feeds, speeds, and toolpath strategy improvements — track and report cycle time savings

Support junior operators and apprentices, providing on-the-job guidance on setups and machining technique

Liaise with the estimating team to provide realistic cycle time and tooling cost inputs for new enquiries

Essential experience

Minimum 4 years of CNC programming and setting in a precision subcontract environment

Proven ability on multi-axis turning and milling (4th / 5th axis); mill-turn experience highly desirable

Fluent in Fanuc G-code; Mazatrol experience advantageous

Proficient with Mastercam or equivalent offline CAM (SolidCAM, GibbsCAM, or HyperMill considered)

Ability to read and interpret engineering drawings including GD&T to BS EN ISO 1101

Machining of exotic materials: titanium (Ti-6Al-4V), Inconel 718, 17-4PH stainless

Time-served apprenticeship or NVQ Level 3 in Engineering Manufacture preferred
